# Best Bilingual Schools in Hong Kong

Hong Kong · Curriculum

Hong Kong looks like a Cantonese city and reads like a Mandarin one. The streets and most homes run on Cantonese; the bilingual international schools, almost without exception, run on Putonghua. Families arriving from London or Singapore expecting to graduate a child fluent in the language they hear in Causeway Bay usually discover, around Year 3, that the school's Chinese stream teaches simplified characters and the national language of the mainland.

Mandarin carries the global utility, university recognition and teacher pipeline; Cantonese has neither a standardised script for instruction nor a serious examination route. The result is a tier of schools, led by Chinese International School, The ISF Academy, Victoria Shanghai Academy, Yew Chung International School and Canadian International School, that run a 50/50 or close-to-it split in English and Mandarin, alongside mother-tongue schools (French, German, Korean, Japanese) pairing their national curriculum with English.

What "bilingual" means here

The label spans three setups, and the differences matter.

Structural bilingual. English and Mandarin teachers share classroom time, often 50/50 or co-teaching with both adults present. CIS runs equal hours through primary; ISF runs Mandarin-medium subject teaching alongside English; VSA delivers PYP and MYP bilingually; YCIS runs pure co-teaching, with a Western and a Chinese teacher in every primary classroom for the full day. Time on task is measured in hours per day, not periods per week.

Mother-tongue plus English. French, German Swiss, Korean and Japanese international schools run national curricula in the home language with English as a serious second medium. GSIS is the cleanest case: a German Gymnasium stream to the Abitur sits alongside an English National Curriculum stream to the IB Diploma. These are dual-stream schools, not bilingual classrooms in the CIS sense.

Mandarin programmes inside English-medium schools. Stamford American, Nord Anglia and Kellett run substantial daily Mandarin blocks. Enrichment programmes that produce competent second-language speakers, not balanced bilinguals. The distinction is whether maths, science and humanities are ever taught in Mandarin. At the structural-bilingual schools they are; at the rest they are not.

The strong bilingual schools in Hong Kong

Chinese International School

Braemar Hill, Hong Kong Island. Founded 1983. Ages 4 to 18. Full IB continuum (PYP, MYP, DP, CP). CIS and NEASC re-accredited 2021. Fees HKD 216,100 to 342,800. Debenture on entry.

CIS is the city's first bilingual international school and remains the reference point. English and Mandarin teachers share equal classroom time through primary, and the Mandarin commitment carries into the upper school as a Language A or B option. IB DP 2025 average 38.95, 99% pass rate, 49% scored 40+, 28% bilingual diploma. Around 1,500 pupils. The debenture reshapes the all-in first-year cost.

The ISF Academy

Pokfulam. Founded 2003 by the late Nobel laureate Sir Charles Kao. Ages 5 to 18. IB MYP and DP. Fees HKD 240,320 to 303,530.

ISF is the Mandarin-immersion alternative to CIS, with bilingual Mandarin-English instruction from Foundation Year through to the upper school. All senior students sit the IB Diploma, with recent cohorts averaging around 40 points and a substantial share earning the bilingual diploma. Around 1,500 pupils on a purpose-built Pokfulam campus, with a clearer Chinese cultural identity than CIS.

Victoria Shanghai Academy

Shum Wan, Aberdeen. Founded 2004. Ages 6 to 18. Full IB continuum (PYP, MYP, DP). Fees HKD 181,200 to 255,600.

VSA was Hong Kong's first through-train IB World School delivered bilingually, with Mandarin and English co-running PYP and MYP. Around 2,100 pupils and a non-debenture fee structure materially below CIS and ISF. The Diploma leans English-medium with Mandarin as a Language A; bilingual diploma rates are lower than at CIS but the primary years are genuinely 50/50.

Yew Chung International School

Three campuses across Kowloon Tong. Founded 1932. Ages 1 to 18. English National Curriculum plus YCIS Chinese Language and Culture programme; HKDSE pathway available. Fees HKD 223,036 to 268,640.

YCIS is the co-teaching model in its purest form: a Western and a Chinese teacher in every primary classroom for the full day, with co-principals at each campus. The in-house Chinese Language and Culture programme is more structured than most third-party Mandarin curricula. Around 2,200 pupils across Kowloon Tong. Exit qualifications are IGCSE and either A Levels or HKDSE rather than the IB Diploma.

Canadian International School

Aberdeen. Founded 1991. Ages 3 to 18. Full IB continuum plus Ontario Secondary School Diploma. Fees HKD 142,780 to 261,500.

CDNIS pairs a Mandarin spine with an unusual dual-diploma structure: every Grade 12 student graduates with both the IB Diploma and the Ontario Secondary School Diploma, with Canadian-specific subjects from Grade 9. Mandarin starts in Pre-Reception and runs through to the Diploma as a Language A or B option, with a meaningful share taking the bilingual IB Diploma. The 14-storey campus sits close to VSA geographically; bilingual depth is real but Mandarin hours per week are below CIS and ISF.

Singapore International School

Aberdeen. Founded 1991. Ages 3 to 18. Singapore MOE bilingual primary; IGCSE and IB Diploma in secondary. Fees HKD 103,000 to 254,900.

SISHK runs the Singapore MOE curriculum from Nursery through Primary 6: a structurally bilingual English-Mandarin programme with the rigour and pacing of the Singapore system. Secondary moves to IGCSE and the IB Diploma, English-medium with Mandarin retained as a subject. The bilingual phase is concentrated in primary. SISHK is the only Hong Kong school running the MOE model.

Po Leung Kuk Choi Kai Yau School

Piper's Hill, Kowloon. Founded 2002. Ages 5 to 18. Through-train British and IB Diploma. Fees HKD 99,825 to 146,927.

CKY runs both Mandarin and Cantonese in its language programme, unusual in this segment. Founded by the Po Leung Kuk charitable organisation, the school finishes on the IB Diploma. Fees sit at roughly half the CIS or ISF level, and the school is academically demanding. The cohort is predominantly local Hong Kong families seeking an internationally recognised exit.

Where the trade-offs land

Mandarin depth vs international peer group. CIS, ISF and VSA deliver the deepest Mandarin, but the cohort skews Hong Kong Chinese; expat families accept a less international peer group than at ESF or HKIS. CDNIS and YCIS balance more evenly. The mother-tongue schools deliver national-language fluency rather than Mandarin.

Bilingual diploma rates. A useful proxy for whether bilingual delivery survives into the upper school. CIS 28%, ISF in a similar band, CDNIS double-digit. VSA's diploma is more English-leaning; YCIS uses A Levels and HKDSE, so the metric does not apply.

Cantonese. No school in this segment delivers Cantonese as a structural medium. The Cantonese-medium route is the local DSS schools (Diocesan Boys', Diocesan Girls', St. Paul's Co-ed), competitive on admission and rarely chosen by international-track families.

Fees. CIS and ISF run HKD 240,000 to 340,000, with CIS adding a debenture. CDNIS and VSA sit in the HKD 180,000 to 260,000 band without debenture. SISHK and CKY run materially below. The mother-tongue schools sit mid-market.

How to read a bilingual claim

A school's marketing material says little. Three questions cut through.

How many hours of Mandarin or Chinese instruction per day, by year group? At CIS and ISF the answer is measured in hours. At a strong enrichment school it is one or two periods. Anything below five hours a week is supplementary.

Are non-language subjects ever taught in Chinese? Maths, science, humanities. If the answer is no across the board, the school is English-medium with a Mandarin programme.

What share of the senior cohort takes the bilingual IB Diploma, or equivalent? A school running structural bilingual delivery should publish a percentage. The number tells you whether the claim survives into the years that matter for university recognition.

FAQs

Is Mandarin or Cantonese taught in Hong Kong international schools?

Almost universally Mandarin (Putonghua) with simplified characters. Cantonese as a medium of instruction is limited to local DSS schools and a handful of programmes that include both, such as Po Leung Kuk Choi Kai Yau. Families relying on school for Cantonese will be disappointed.

What is a bilingual IB Diploma?

A diploma earned by students completing two Language A subjects, or one Language A plus a humanities or science in a second language, at sufficient grades. CIS reports around 28% of its 2025 cohort earning it; ISF a similar share; CDNIS double-digit. The cleanest single metric of whether bilingual identity carries into the upper school.

Which bilingual school has the strongest IB results?

CIS 2025 average 38.95, ISF around 40, VSA in the high 30s, CDNIS in the mid-30s. Order shifts year to year, but CIS and ISF publish the strongest combined picture of bilingual delivery and IB average.

Can a child join a bilingual school without Mandarin?

At CIS, ISF and VSA, joining without Mandarin becomes harder year by year. Reception and Year 1 entry is common; from Year 3 onwards the classroom assumes a working level. YCIS and CDNIS are more flexible for mid-school joiners, with structured catch-up programmes.

Does French, German, Korean or Japanese count as bilingual?

In the dual-stream sense, yes. FIS, GSIS, KIS and JIS all run substantial second-language delivery alongside the home language. Graduates leave fluent in the home language with strong English. A different bilingual outcome from English-Mandarin, but a structural one rather than a language programme bolted onto a single-medium curriculum.
